  "The 
  live 
  bugs 
  were 
  pres- 
  

   ent 
  in 
  considerable 
  numbers 
  in 
  the 
  wheat 
  field 
  where 
  experiment 
  was 
  conducted. 
  

   In

  10

  turn 
  white."

  reported 
  December 
  7th: 
  "I 
  had 
  a 
  patch 
  of 
  

   millet 
  which 
  was 
  just 
  black 
  with 
  chinch-bugs. 
  I 
  used 
  diseased 
  bugs, 
  and 
  a 
  few 
  

   days 
  later 
  the 
  ground 
  was 
  covered 
  with 
  white-fungus 
  bugs. 
  Success 
  to 
  you 
  in 
  this 
  

   great 
  work. 
  It 
  will 
  be 
  worth 
  millions 
  to 
  the 
  farmers 
  of 
  Kansas. 
  I 
  saved, 
  by 
  using 
  

   the 
  infection, 
  570 
  bushels 
  of 
  wheat 
  and 
  $20 
  worth 
  of 
  millet."

  any 
  part 
  of 
  the 
  field. 
  

   I 
  have

  "In

  Correspondent 
  

   states

  250

  the

  the

  six 
  of

   and

  third 
  experiment

  reported 
  October 
  29th: 
  "The 
  first 
  two 
  

   lots 
  you 
  sent 
  me 
  had 
  no 
  effect; 
  but 
  the 
  third 
  lot, 
  infected 
  with 
  the 
  white 
  fungus, 
  I 
  

   put 
  among 
  the 
  bugs 
  as 
  they 
  came 
  out 
  of 
  my 
  rye 
  field 
  into 
  the 
  corn, 
  and 
  was 
  suc- 
  

   cessful 
  in 
  killing 
  them. 
  I 
  gave 
  some 
  infected 
  bugs 
  to 
  a 
  neighbor, 
  who 
  put 
  them 
  in 
  

   a 
  millet 
  field 
  where 
  the 
  bugs 
  were 
  very 
  numerous. 
  It 
  worked 
  well; 
  the 
  ground 
  be- 
  

   came 
  white

  dead

  June

   "My 
  corn 
  is 
  loaded 
  with 
  bugs." 
  Infection 
  sent 
  June 
  17th 
  and 
  July 
  1st; 
  experiments 
  

   successful, 
  as 
  reported 
  October 
  20th: 
  "About 
  10 
  days 
  after 
  I 
  distributed 
  the 
  infected 
  

   bugs, 
  we 
  had 
  a 
  shower, 
  and 
  the 
  bugs 
  became 
  stupid 
  and 
  disappeared; 
  what 
  became 
  

   of 
  them 
  I 
  know 
  not. 
  The 
  second 
  lot 
  I 
  put 
  on 
  another 
  field 
  and 
  I 
  am 
  convinced 
  

   that 
  they 
  operated 
  quicker. 
  After 
  six 
  days 
  the 
  live 
  ones 
  became 
  sluggish 
  and 
  

   changed 
  color, 
  and 
  in 
  14 
  days 
  had 
  entirely 
  disappeared. 
  One 
  thing 
  that 
  struck 
  me 
  

   was, 
  that 
  right 
  where 
  the 
  dead 
  bugs 
  were, 
  there 
  came 
  a 
  swarm 
  of 
  flies 
  in 
  both 
  fields, 
  

   and 
  in 
  other 
  parts 
  of 
  the 
  field 
  no 
  flies 
  were 
  seen. 
  I 
  am 
  convinced 
  that 
  the 
  bugs 
  are 
  

   as 
  you 
  represent, 
  and 
  of 
  great 
  value 
  to 
  the 
  farmers."

  Infection 
  sent 
  August 
  13th; 
  

   experiment 
  successful, 
  as 
  reported 
  October 
  28th: 
  "The 
  experiment 
  was 
  entirely 
  

   satisfactory 
  in 
  my 
  case. 
  I 
  placed 
  about 
  300 
  of 
  the 
  infected 
  bugs 
  in 
  my 
  field 
  of 
  50 
  

   acres 
  of 
  corn, 
  and 
  waited 
  for 
  results. 
  The 
  corn 
  was 
  too 
  far 
  along 
  to 
  do 
  it 
  any 
  good 
  

   by 
  destroying 
  the 
  bugs. 
  I 
  only 
  wished 
  to 
  be 
  satisfied 
  as 
  to 
  the 
  feasibility 
  of 
  de- 
  

   stroying 
  the 
  bugs 
  by 
  infection. 
  I 
  am 
  satisfied 
  that 
  if 
  all 
  of 
  the 
  farmers 
  would 
  place 
  

   infected 
  bugs 
  in 
  their 
  fields, 
  that 
  the 
  bugs 
  that 
  were 
  not 
  destroyed 
  would 
  damage 
  

   the 
  crops 
  but 
  little 
  and 
  that 
  we 
  might 
  get 
  rid 
  of 
  them 
  entirely. 
  My 
  process 
  of 
  ex- 
  

   perimenting 
  was 
  done 
  in 
  this 
  way: 
  I 
  scattered 
  the 
  live, 
  infected 
  bugs 
  through 
  the 
  

   field, 
  and 
  where 
  I 
  found 
  the 
  bugs 
  the 
  thickest, 
  I 
  placed 
  two 
  or 
  three 
  on 
  stalks 
  I 
  

   marked; 
  these 
  stalks 
  were 
  entirely 
  covered 
  with 
  bugs. 
  In 
  about 
  10 
  days 
  I 
  found 
  a 
  

   great 
  many 
  dead 
  bugs 
  on 
  the 
  marked 
  stalks, 
  and 
  in 
  about 
  two 
  or 
  three 
  weeks 
  I 
  found
